2 Claims. (01. 28033.12)

This invention relates to an adjustable hitch device. More specifically it relates to hitch devices of the type which can be adjusted laterally.

It is desirable when hitching an implement structure to a tractor to be able to adjust the hitch point. Many hitch devices of this type have been provided but they are not satisfactory since they are hard to adjust, and the parts of the hitch become worn during use and allow the suitable type of hitch connection could housed in place of the releasable hitch.

A brace member I! is also pivotally connected to the transverse bar l3 at a point spaced from the pivotal connection of the draft member 14, and has a bent end portion I 8 which extends between the bars I to and lb of the draft member M. A pair of openings I9 are provided in the end portion til at each side of the draft memhitch point to shift freely. 10 her It. A pair of links 2!], each having a bent It is, therefore, an object of the present invenend portion 2|, is inserted in each of the opention to provide an adjustable hitch device which ings l9 at each side of the draft member l4.

Other objects and advantages of the present AS shown in Figure 2 the links 20 extend rearinvention will be apparent to those skilled in wardly along the sides of the draft member M, the art after a careful consideration of the foland the rear ends thereof are bent upwardly. lowing detailed description of the preferred As shown in Figures 2 and 6, a ro er is p structural embodiment, taken in conjunction with vided between the bars Ma and leb and jourthe accompanying drawings, wherein such strucnaled on a pin 24a which is inserted in alined tural embodiment is illustrated, and in which: openings provided in the links 20.

Since the releasable hitch device is old member I3. The roller 23a rolls between the bars and well known to those skilled in the art the I la and lib and the rollers 22 roll along the details thereof will not be described, in fact any 5 sides of the bar Mb. On forward movement of the links 20 the draft member I4 is moved about its pivotal connection to the right and on rearward movement of the links 20 the draft member is moved about its pivotal connection to the left. The links 20 are held in their adjusted position by the crank screw 21, The angular position of the brace member I! is also maintained by virtue of its connection to the links 20, and the draft member 14 is held against lateral movement by the rollers 22 on the brace member [1.

From the foregoing description it is obvious that a novel hitch device has been provided. The hitch can be quickly adjusted and friction between the adjustable parts is eliminated by the use of rollers. 7

It is the intention to limit the invention only within the terms of the appended claims.

What is claimed is:

1. A hitch device comprising a draft member pivotally mounted on an implement structure, a brace member pivotally mounted on the implement structure at a point spaced from the pivotal mounting of the draft member and extending across the draft member, rollers mounted on the brace member and associated with the draft member, links connected to the brace member and extending along the sides of the draft memher, a roller mounted between said links and associated with the draft member, and a crank screw mounted on the draft member and operatively associated with the links for adjusting the brace member to effect adjustment of the draft member.

2. A hitch device comprising a draft member pivotally mounted on an implement structure and adapted to move in a horizontal plane, a brace member pivotally mounted on the implement structure at a point spaced from the pivotal mounting of the draft member and adapted to move in a horizontal plane, rollers mounted at the end of the brace member, and associated with the draft member, links connected to the brace member and extending along the sides of the draft member, a roller mounted between said links and associated with the draft member, and a crank and screw mounted on the draft member and operatively connected to said links for adjusting the brace member to effect, lateral adjustment of the draft member.
